I hope FP line allows guests to enjoy the queue/pre-show for this stuff. I was bummed that I didn't get to experience any of it when I did FP for Flight of Passage at Pandora. You pretty much bypass the whole thing and miss out on a lot of great build up and, IMO, part of the attraction itself by just going straight to the on-ride part. These days, the queues and pre-shows are so much more than what they used to be and if they're going to put so much time and effort into making these things amazing, it's a shame to essentially punish guests and give them a lesser experience because they opted to do FP for it.
IDK but this never bothered me. If people want the stuff in the queue they have the option of standing in the regular. line. I think the thinking is most FP users either just want to get on ASAP or have seen enough of the queue to the point they no longer care. And I'll be honest if I'm always just getting a FP for a certain attraction I basically fall in both of these camps.
